Family NITIDULID^. 



13. Prometopia quadrimaculata, Motsch, 



This is evidently a widely distributed species, as it was described 

 by Motschulsky from Ceylon, and there is a specimen in the British 

 Museum from the Philippine Islands. A long series was collected 

 by Mr. Andrews, showing that the species varies considerably, and 

 little importance need therefore be attached to its failure • to 

 correspond in every respect with the description. Motschulsky 

 mentions an impressed median line on the thorax, of which I can 

 find no ti'ace ; and Reitter, in a table of the Oriental species of 

 tliis genus, characterizes P. quadrimaculata as having the basal spot 

 of the elytron " peu developpee transversalement," whereas the 

 development of this spot differs greatly in different specimens, 

 sometimes extending transversely to the suture and sometimes 

 upwards to the base of the elytron. 



14. Stelidota orientalis, Arrow, sp.n. 



Elongato - ovalis, convexa, fusco - niger ; capite prothoraceque 

 punctato-rugosis, fulvo-setosis, prothoracis lateribus arcuatis, rufo- 

 liavis, angulis anticis obtiisis, posticis acutis, disco prope basin 

 leviter bifoveolato ; elytris costatis, costis setosis, interstitiis grosse 

 seriato-punctatis.punctis setiferis, marginibus maculisque rufo-llavis. 



Long. 3 mm. 



The colour is a deep brownish-black, with the margins of thorax 

 and elytra and markings on the latter reddish yellow. The pattern 

 on each elytron consists of a spot bordering the scutellum, another 

 beneath near the suture, a wavy fascia beyond this extending 

 nearly across the elytron, and another between the first and second 

 spots reaching the external but not the internal margin. There 

 are two large but not deep impressions near the base of the 

 prothorax. 



The British Museum collection contains a specimen of this species 

 from Macassar. Another, from ^Ir. Andrew Murray's collection, 

 bears the unpublished name of Stelidota orientalis, Motsch.
